tags in parallel music gives "Bars in parallel music don't have the same length"

[Helge Hafting]

This file compiles to a correct PDF, but lilyponds complaint about
different bar lengths is wrong.

The "skipped" note is not engraved, so the bars have the same length. 
But lilypond complains as if everything is rendered.

I sometimes use tags so that midi and PDF gets different notes,
usually to work around some rendering problem. I just got
a solution so I don't need this to work just now, but
thought you might want to know anyway.

The problem here is that such warnings are very useful when they are 
always correct. They can point out typos. But wrong warnings means they 
get ignored, and that could mask real problems in the same music.
